PBM is probably older than GIF and still has software support

though apparently not directly in browsers! (I would have expected it did, but I couldn't get browsers to render PBM files directly.)

Netscape Navigator supported PBM (at least in some versions you could even write directly into a frame/window via JS in order to compose an image on the fly).

I completely forgot about that! I very vaguely remember experimenting with it, and I think I never got it to work. I can't find anything on it now, though.

Huh! So in that case, it could be that there's an old PBM file somewhere that could be a contender for this record.
